We recommend matching the part number on your original part with the part number listed on this page to ensure compatibility.
While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.
We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.
Please don't hesitate to contact us with any questions. We're here to help!
The technology of today's electronic devices has increased current handling capacity. The additional heat buildup places great
demands on heat sink materials. GC offers a complete line of heat sink compounds to meet these demands. The HTC product offers
over twice the thermal conductivity of conventional products and is available in silicone and non-silicone versions. The water-soluble
heat sink grease offers excellent thermal conductivity and easy cleanup. The standard silicone and non-silicone products continue to
meet most requirements. See chart for typical properties.
Silicone (Z9)
Industry standard zinc oxide filled silicone heat sink
grease for most applications. Will not soften at elevated
temperatures or dry out or harden. Meets Mil. Spec.
